[Group psychotherapeutic factors in a self-assertive group].

The technique of group psychotherapy has recently been introduced to the practice in self-assertiveness training group. This study aims to assess various group factors that are hypothesized to be effective in the group process in a self-assertive group. Subjects of the study were participants in a 13-member self-assertiveness training group, with 4 female nurses and 8 male employees and 1 male student. The average age of this group was 35.2 years. Assessment of the group was based on Yalom's concept of twelve therapeutic factors in the group process. The results showed that 'identification', 'The existential factor' and 'interpersonal learning-input' were the three most important factors demonstrated during the group process. There were no significant age and gender differences in the above 'identification' and 'existential' factors. However, different beneficial factors were found for each group: for subjects aged 40 and above and males, it was 'interpersonal learning-output'; while in those with aged under 40 and females, 'universality' was more important than 'interpersonal learning-input'. Comparison of therapeutic factors among different groups was attempted. The above results were found different from patient groups, or the groups of university students. The discrepancy is due to different composition and tasks of each group.
